Verdict
Vitamin and Stack Tracker AI both sit at 4.1 stars, but that hides the real split: 62% of Vitamin's written reviews are positive against 0% of Stack Tracker AI's. Vitamin also leads on ratings volume (89 vs 2) and iOS requirement (17.0 vs 26.0). Stack Tracker AI's advantage is update cadence (fortnightly vs every 3 months). On price, rating, ads and in-app purchases there is nothing between them.
